UNPACKING
The Q – Zone has been designed as a rugged piece of professional equipment. It contains a high specification modern electronic PCB assembly
and should be treated with care.
The packaging of the unit is specifically designed to safely transport this product. In the unlikely event of the product requiring servicing, it is best to
return it in this packaging.
All units are factory set for 220-230v operation. Units factory made for 110/120V supply are clearly marked on the back and should not be
connected to any higher voltage power source.

The wires in the IEC/CEE mains lead are coloured: Earth: Green/Yellow Neutral: Blue Live: Brown
MOUNTING THE UNIT
This unit has been designed for rack mounting use, in a Racking enclosure made to BS5954, IEC297 or Din 41494 standards.
DO NOT USE RACKS NEAR HEATING DUCT OUTLETS, APPLIANCES OR RADIATORS.
Care is required when installing these units in a rack. It is advisable to put the Rack on its back, then place all the other equipment being fitted
to the rack into it before tightening the retaining screws.

Using the Q-zone
The Input Channels
The Mic & Line inputs use XLR connectors and are designed to suit a wide range of BALANCED or
UNBALANCED signals. A stereo signal from a Mixer or DJ console can be fed either into the dual Line
input XLR’s or the pair of phono sockets. PLEASE NOTE these signals will be summed into MONO
for zoning. The use of a professional dynamic microphone is recommended, because this will be LOW
IMPEDANCE and BALANCED. You can use low-cost HIGH IMPEDANCE mics, but the level of
background noise will be higher as well as having poor sound quality.

Mixer to Mixer Link from Q-Mix
The Q-Mix can be to easily linked into a Q-zone
via the mixer to mixer link.
A Standard screened 5pin Din to 5pin 180º audio
link leads are recommended for this application.

The Signal Input Controls
The Input Link Level
This knob sets how much of the source signal is sent into the zoner. Too high and the signal will distort as it overloads the channel. Too low, and
the level of background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer.
The RED peak level LED, is set show at 0dB (0.775v) and is designed to indicate the onset of clipping (distortion), however occasional flashing of
this will be observed from very dynamic sources, without causing any undesirable effects.
Setting the knob at 9’oclock gives approximately unity gain for the LINE input. Note that some sound equipment that is intended for domestic use,
operates at a lower level (-10dBV) than pro-audio gear and will therefore need a higher setting to get the same level.
Contour Control
A pseudo Master Graphic EQ; turning this knob clockwise produces the infamous ‘smile’ curve,
that most users prefer. Fully clockwise will produce a really deep bass and a give very bright top end.
Vocal Overide
Use of this feature will cause all channels to ‘DUCK’ (Auto Fade) ‘IN USE’ indicated by a LED.
This feature is ideally suitable for PAGING or SPECIAL ANNOUNCEMENTS
Volume Knob
Use this to control the PA Microphone level of signal going to the Master Volume Stage.
Bass Control
Turn knob clockwise to boost low (bass) frequencies of the Microphone
Treble Control
Turn clockwise to boost high (treble) frequencies of the Microphone - Set both the knobs at the 12 ‘o clock position for a flat response

Fire Cut Out
This Feature when connected to a fire alarm system will stop sound in all zones, but allows the emergency announcements made via the PA
mic channel to be heard in all areas, even if not selected at the time.
A Red LED shows that the Fire Cut Out relay is activated, pressing the button below will re-set the Fire Cut Out relay if accidentally tripped.
Master Volume Control
Does exactly what is says on the tin - it controls the overall volume being fed into the 6 output zones of the Q – zone
Zone Level Controls
Depress the appropriate button to send the signal to the areas
selected; the green LED shows the zone is activated.
The Zone Level Control sets the volume for each zone; however
if the Master Volume is set too low then this function will have
less effective range.
These level controls are also able to be remotely changed, but
if these are also set too low then the remote function will not
have effective range.
Please note that the remote maximum output level is governed by the Zone Level setting
Special Connections
Fire Alarm Connector
2 Way screw terminal connector for connection to the standard open contact relay circuit found
on all on approved Fire Alarm Systems
(There is no polarity to these 2 connections) If in doubt consult your service provider.
8 Way Remote Terminal
The Volume Levels of each of the six zones can be controlled from a remote location by using
the 8 way plug–in screw terminal provided.
Each channel is clearly marked at the back and can be easily hooked up with just 2 wires for each zone
Connect 1 wire to the required channel and 1wire from point G, to a Qzone remote volume control unit.
(Small Diameter cable can be used - it does not need to be shielded)
Zone Outputs
All zones have high level balanced line outputs; this enables long cable runs with very low distortion, by eliminating main hum, RF interference,
voltage drops & noise. They can drive 10V RMS into 600
Ω
with an output impedance of 50
Ω
The outputs should be made with Female XLR’s
with the connections as show.
All outputs must use screened cable.
It is recommended that on very long runs that
‘LSOH single twisted pair foil wrapped cables’ be used.
DO NOT USE 3 CORE MAINS CABLE OR SPEAKER CABLES
Pin 1 = Screen Pin 2 = Hot Pin 3 = Cold
Power Connection
The wires in the IEC/CEE mains lead are coloured: Earth: Green/Yellow Neutral: Blue Live: Brown
As these colours may not correspond with the colour markings identifying the
terminal in your plug proceed as follows: Green/Yellow wire must be connected to
the terminal which is marked with the letter E or coloured Green. - Brown wire
must be connected to the terminal which is marked with the letter L or coloured
red. - Blue wire must be connected to the terminal which is marked with the letter
N or coloured black.
To get the most out of your system, It is important to have the right connections so please check to
make sure all of your hook up cables are correct and you are using the right type of cable.

Although the greatest care has been taken in the manufacture of this mixer, the possibility remains that faults could occur during use or difficulties
could be experienced during initial installation.
The cause, however, will rarely be found to be internal to the be the mixer. Below is a list of symptoms and possible causes. Some of the
suggested causes may appear obvious, but they can be easily overlooked.
Under no circumstances should you open the mixer; as this is dangerous, and will expose you to mains voltages; it will also invalidate all rights
under the guarantee.
1. After turning on the ‘power’ switch the 'power' indicator does not light-
The mains plug is not pushed far enough into the mixer.
Check there is a supply to the mains socket.
Check supply using an alternative electrical appliance.
The mains input fuse is broken, at back of mixer, replace using QB 250mA 20mm fuse.
2. When the controls are advanced no sound is heard-
Check the input signal is connected to input socket.
Check the input signal is connected to channel being used
Move input plug to another channel, or use controls on connected channel.
3. Even when the output is low, the output sounds distorted-
Check the input gain is not too high - peak LED will be on
Check the input signal is not too high - peak LED will be on
4. Check the mic is plugged into a mic channel
Check the mic cable a balanced 3 wire type
